HEYA!!!!!!
Here is your answer :
__________________________
Given,
Mean = 100. Number of observations = 10
If 55 is added then the mean is,
Mean = Sum of all observations / Numbe r of observations
100 = x / 10
1000 = x
Sum of 100 observations = 1000
If 55 added the sum is 1055
New Mean = 1055/11
= 95.9
